#include <disp/lineplot.h>

class DISPLIB::LinePlot

Simple x / y line-series QWidget rendered with QPainter (no Qt Charts dependency).

Supports multiple series, a settable title and x / y labels and auto-ranging axes. Series are stored as QVector<double> pairs and re-drawn during paintEvent.

Constructs a line series plot.

Parameters:

  • parent : *QWidget ** If parent is nullptr, the new widget becomes a window.

LinePlot(y, title, parent)​

Constructs a line series plot.

Parameters:

  • y : const QVector< double > & The double data vector.

  • title : const QString & Plot title.

  • parent : *QWidget ** If parent is nullptr, the new widget becomes a window.

LinePlot(x, y, title, parent)​

Constructs a line series plot.

Parameters:

  • x : const QVector< double > & X-Axis data to plot.

  • y : const QVector< double > & Y-Axis data to plot.

  • title : const QString & Plot title.

  • parent : *QWidget ** If parent is nullptr, the new widget becomes a window.

~LinePlot()​

Destructs the line series plot.

setTitle(p_sTitle)​

setYLabel(p_sYLabel)​

Sets the label of the y axis.

Parameters:

  • p_sYLabel : const QString & The y axis label.

updateData(y)​

Updates the plot using a given double vector without given X data.

Parameters:

  • y : const QVector< double > & The double data vector.

updateData(x, y)​

Updates the plot using the given vectors.

Parameters:

  • x : const QVector< double > & X-Axis data to plot.
